Pruvit Keto OS has become extremely popular as a way to stay in keto even if you have the odd carb slip up. Endorsements by such influencers as Joe Rogan have earned Pruvit a loyal following. So, we thought it was about time we put this exogenous ketone supplement to the test in order to separate fact from fiction.
In this Pruvit Keto OS review we give you the hype free facts so you can decide whether Keto OS really works?
What is Pruvit Keto OS?
Pruvit Keto OS is an exogenous ketone supplement. As such it is made up of a combination of BHB salts that are designed to deliver synthetic ketones into the bloodstream. This supplements the body’s natural efforts to get into ketosis through carbohydrate restriction. It has been scientifically established that getting into and staying in a ketogenic state helps people lose body fat.
By delivering external ketones into the bloodstream, BHB salts fool the body into thinking that it is already in ketosis. This can help to push a person over the edge and into ketosis. When that happens, they will start converting stored body fat into energy.
The people behind Pruvit Keto OS state that taking this supplement can help you to get into ketosis in as little as half an hour (more on that claim later!) Pruvit is a Hong Kong based company who has been in the supplement industry for a number of years.
Keto OS comes in powder form, with each serving being between 12-16 oz. It can be mixed either with water or any zero carb liquid (taking it with a carb infused beverage would defeat the purpose of taking this product!).
Each serving of Keto OS delivers 50cc of BHB based exogenous ketones to your system.
Keto OS comes in a caffeine added and a non-caffeine version (known as charged and uncharged). In addition to BHB, the other ingredient is MCT Oil.
Keto OS is available in two flavors:
- Orange Dream
- Chocolate Swirl
The Pruvit Company
Pruvit is a nutritional supplement business that has been operating online since 2013. Their first product was the one that has become their most popular, Pruvit Keto OS. That product has the distinction of being the first exogenous ketone supplement drink on the market. It is interesting to note that the original Pruvit Keto OS was met with a large number of negative reviews, mainly centered around the cost. The formula was reinvented to become Pruvit Keto OS Max. This version was far more favorably received.
Pruvit market themselves as the world’s leading ketone supplement provider. Their official website can be found here.
Pruvit is set up as a multi level marketing company, which makes some people dubious about just how trustworthy it is. However, you can purchase all Pruvit products through Amazon or the official website without having anything to do with that side of the business.
In addition to their range of products, Pruvit also run what they call ‘Kato Kademy.’ This purports to be a ketogenic diet training school. However it is very expensive and there is no guarantee that you will find anything there that you can’t get on a free website like the one you are visiting right how!
The Pruvit line of supplements includes the following products:
- Keto Up
- Keto OS NAT
- Keto OS Max
- Keto OS Unleashed
- Pruvit Pulse App
- Ketos OS NAT Holy Grail
- Keto REBOOT
- Keto KREME
At the time of writing there have not been any lawsuits filed against Pruvit.
The main competitors to Pruvit in the ketones supplement space are:
The company operates all over the world with regional websites linking from the main site. Pruvit Canada has recently gone live.

Keto OS Benefits
Let’s now take a look at the things that Keto OS may potentially do. We’ll then see how good it actually is at delivering. So, here is what Keto OS may do:
- Help you get into keto faster – consistently cutting out the carbs in order to kick the body into the fat-burning state of ketosis is hard work. We could all do with a little help. And that is precisely what Keto OS promises to offer. The addition of exogenous ketones delivers reinforcements that have the ability to push you right into the fat-burning zone.
- Help you get rid of body fat – getting into keto will force your body to switch from a glucose burning to a fat-burning energy system. As a result, you will be burning off stored body fat to supply the energy that your body needs to function. Exogenous ketones will also help to suppress your appetite. In a 2014 study, a keto inducing diet led to a 50 percent reduction in appetite.
- Ward off keto flu symptoms – when you transition to keto, you will, unless you are very lucky, experience what is known as the keto flu. Symptoms are similar to the real flu. Exogenous ketones have the ability to help fight these effects. They provide energy to overcome lethargy, boost brainpower to overcome fogginess and help overcome nausea.
- Increase Endurance – Extra ketone means extra energy. They have also been shown to reduce lactic acid buildup and prevent the catabolism of muscle tissue. All of this means that you will be able to exercise harder for longer.
- Boost Brain Power – the keto diet was first developed in the 1920s to treat children’s epilepsy. Since then there have been many brain benefits associated with the ketogenic diet. Keto is also able to improve the memory of rats in a number of studies.
My Pruvit Keto OS Results
Ok, so we have seen all of the claims and potential benefits of Pruvit Keto OS. But do they really stack up? Here is my experience with Keto OS.
Because I am not a keto newbie, I wasn’t suffering from the keto flu while I was taking Pruvit Keto OS. As a result, I am not in a position to state whether it works to dampen the effects of the keto flu. But I can comment on its ability to provide extra energy for working out.
Pruvit Keto OS gave me a noticeable increase in energy for my workouts. I had more endurance, too. When taking the Charged option, the results in terms of energy production were even more pronounced. I also had a significant increase in training focus.
My fat loss was steady both while on and off Pruvit Keto OS, so it is hard to tell how much of an effect the supplement had.
My overall impression was that Pruvit Keto OS did a good job of boosting my training energy to allow me to train harder in the gym. Keep in mind, though that this product is not sold as a pre-workout supplement. The results I received in terms of fat loss were not what I was hoping for.

The Experience of Others
So, now that you know my experience with Keto OS, let’s take a look at what others have said about it. There are a lot of reviews online from real Keto OS users. Here’s a random sampling:
Toni was pretty good about sticking to a keto diet during the week. But it was a different story when the weekend rolled around. That was when she needed a boost to keep her on track. That is exactly what Keto OS did for her. In fact, it allowed her to lose an extra 8 kg!
Jeanette gave Keto OS a 3 month trial. She found that it did a good job of boosting her energy levels and controlling her hunger pangs. Both of those actors contributed to her weight loss. However, she wasn’t sure whether the exogenous ketones actually helped her lose more weight in themselves.
Popular Podcster Joe Rogan from the Joe Rogan experience promoted Pruvit Keto OS on his show. Joe lamented that fruit woud take him out of keto. He found that supplementing with Keto OS allowed him to enjoy his fruit – and stay in keto!
Here’s what Joe has to say about Pruvit Keto OS . . .
‘The big difference, with carbs, I experience inflammation. More soreness, fatigue, insulin crash… all the factors that don’t happen when I eat high fat, low carb.’
It is important to keep in mind that results from Pruvit Keto OS only cone when you are exercising and eating low carb at the same time.
Keto OS Versions
There are three different versions of Keto OS as follows:
- Keto OS
Flavors – Orange Dream / Chocolate Swirl
- Keto OS Max – beefed up ingredients
Flavors – Maui Punch / Swiss Cacao
- Keto OS Nat – Nutritionally Advanced Technology
Flavors – Splash / Raspberry Punch
Keto OS Taste
Exogenous ketone supplements do not have a very good reputation when it comes to taste. With that in mind, it is refreshing to find a brand that isn’t completely horrible. However, neither is Keto OS as mouth watering as the company claims. The taste is pretty good on all flavors, but not outstanding.
The general consensus is that Chocolate Swirl is the tastiest of all the flavor options.
The price that you have to pay for the enhanced flavor in the Keto OS range is that they contain extra carbs. That will diminish their impact in terms of helping you get into a state of ketosis.
Pruvit Keto OS vs Perfect Keto
So, how does Keto OS stack up against Perfect Keto?
In my analysis, Perfect Keto is a better exogenous ketones supplement. Here’s why . . .
- When it comes to taste Perfect Keto knocks it out of the ball park. While the best Keto OS flavor is good, the majority of Perfect Keto flavors are great!
- Perfect Keto is less expensive than Keto OS and it provides you with fewer calories and zero carbs!
The Pruvit Diet
There is no point taking this product unless you are following a low carb diet. You should keep your carb macros down to 5 percent, which 70 percent fat and 25 percent protein. Be sure to include ascorbic acid, mct oil and other mct products in your diet to help transition to a fat ketone operating energy system. Ascorbic acid, by the way, is otherwise known as Vitamin C.
What is Keto OS Pruvit?
Keto OS is a form of exogenous ketones. This helps you to get into a state of ketosis faster than if you followed a normal low carb diet without supplementing. The product will put more ketone bodies into your bloodstream. Extra benefits of the product are that when you have a fat based ketone operating system, you will produce a lot more energy to power you through your workouts.
Are there any studies behind this product?
The official website does mention some studies but it does not provide any links to their source. Most studies that are done on this topic are done on rats rather than on humans. That’s because rats have a similar physiology to humans.
What are the side effects of Keto OS?
Side effects are not mentioned on the official website. However, a review of the ingredients in this product, along with user experience, shows the following potential side effects:
- Stomach upset
- Abdominal pain
- The jotters
When you enter into a state of ketosis for the first time, you will likely suffer common side effects that occur during the induction phase of this diet (link to induction article). Be sure to drink more water, take an mct supplement and digestive enzyme to help your liver cope with the extra demand that it will face.
Does Keto OS cause bloating?
It is quite normal for this product to cause some bloating. As result you might want to try taking a digestive enzyme. This will also help the liver to process the extra ketones. You should also drink more water when you follow the keto diet.
Is Keto OS safe?
Yes, Keto OS is a safe supplement. All of the ingredients are completely natural. The Caffeine added version may cause an energy crash for some people, however.
There are general side effects that come with induction to the keto diet and these should rightly be included here. They include:
- Brain Fog
How long will this product stay in my body?
There is no set answer to this question because it is dependent upon how much exercise you do and the types of foods you eat. To determine how many ketones you have in your body and quickly they are exiting your body, use a ketone analyser that is able to test the number of ketones in your breath or urine.
What is the cost of Keto OS?
Keto OS is one of the more expensive exogenous ketones boosting supplements on the market. However, the price varies across the internet. Because there are lot of less than reputable dealers out there, we would suggest buying from Amazon (link to Amazon) or the official website.
Can Keto OS help me to get in ketosis faster?
The exogenous ketones that this product puts into your bloodstream are designed to fool your body into ketosis. But this will only happen if you are nearly there naturally. To do that you have to be cutting your carbohydrates way back in order to reduce the amount of glucose in your body.
Is there added caffeine in Keto OS?
You have the option of buying a caffeine version, which is called ‘Charged.’ This will give you about the equivalent of a cup and a half of coffee in every dose.
